Abstract
The invention discloses a quartering hammer drill shank bucket tooth and a manufacturing method thereof. The quartering hammer drill shank bucket tooth is characterized in that a bucket tooth body is an approximate cone, the front end of the bucket tooth body is an operation part, the bucket tooth body is internally provided with a drill shank inserting cavity, the horizontal cross section of the drill shank inserting cavity is round, and the bucket tooth is obtained through smelting, casting, pouring, quenching and tempering. The quartering hammer drill shank bucket tooth provided by the invention is sleeved on a quartering hammer drill shank when in use and is closely matched with the quartering hammer drill shank, and when the quartering hammer drill shank bucket tooth is used in a crushing operation, firstly, the bucket tooth is worn, so the bucket tooth has the protective action on the drill shank, the service life of the drill shank is prolonged, and the operation cost is reduced.
Description
Technical field
The present invention relates to a kind of parts of disintegrating machine, be specifically related to crushing hammar drill rod Tooth structure used, the invention still further relates to the manufacture method of this bucket tooth.
Background technology
Domestic and even various quartering hammers (being commonly called as woodpecker) that produce in the world, all adopt superior alloy steel bar fine forge piece at present, and the drill rod that forges out through repeatedly normalizing, Quenching Treatment carries out work.Although good drill rod long service life, intensity are high, quartering hammer is all generally the running of 24 hours ultra-long times, excess load, under the bad working environments condition.The distortion that the drill rod rate of wear is very fast, have, even fracture.At present, a domestic good drill rod price is 2000 yuan of left and right, and import drill rod price reaches more than 3000 yuan, and cost is expensive, if drill rod is scrapped words frequently, will greatly increase production cost, and when changing drill rod, must the dismounting quartering hammer, and time-consuming, take a lot of work.
Summary of the invention
For problems of the prior art, the invention provides a kind of bucket lip for drill rod of breaking hammer and, bucket tooth is sleeved on crushing hammar drill rod, extends the service life of crushing hammar drill rod.
The object of the present invention is achieved like this: a kind of bucket lip for drill rod of breaking hammer, bucket tooth body are an approximate circle cone, and bucket tooth body front end is operate portions, are provided with drill steel in the bucket tooth body and insert the chamber.The horizontal cross-section that drill steel inserts the chamber is circular.
A kind of method of making bucket lip for drill rod of breaking hammer, at first carry out melting: be that raw material advances melting with iron, carbon, manganese, silicon, chromium, aluminium, sulphur, phosphorus, rare earth, smelting temperature is 1580～1620 ℃, and molten steel is cast, 1560～1580 ℃ of casting and pouring temperature; After completing, casting quenches at 900 ℃, temperature retention time 2 hours, and carry out tempering, temperature after quenching is completed: 450 ℃, temperature retention time: 4h obtains bucket lip for drill rod of breaking hammer;
During melting, each material is by percentage to the quality: carbon: 0.27～0.30 ﹪, and manganese: 0.8～1.1 ﹪, silicon: 01.50～1.70 ﹪, chromium: 1.40～1.60 ﹪, aluminium :≤0.08 ﹪, sulphur, phosphorus≤0.03 ﹪, rare earth Re:0.01 ﹪, surplus is iron.
Bucket lip for drill rod of breaking hammer provided by the invention is sleeved on during use on crushing hammar drill rod, closely cooperates with crushing hammar drill rod; in carrying out crushing operation, at first wearing and tearing is bucket tooth, and bucket tooth can play a protective role to drill steel; extend the service life of drill steel, reduced job costs.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is perspective view of the present invention.
Fig. 2 is sectional structure chart of the present invention.
Fig. 3 is the structural representation that installs additional after drill steel.
Fig. 4 is the A-A cutaway view of Fig. 2.
The specific embodiment
Structure of the present invention is as shown in Figure 1: a kind of bucket lip for drill rod of breaking hammer, bucket tooth body 1 are an approximate circle cone, and bucket tooth body 1 front end is operate portions 4, are provided with drill steel in bucket tooth body 1 and insert chamber 2.The horizontal cross-section that drill steel inserts chamber 2 is circular.
The production method of bucket lip for drill rod of breaking hammer: at first carry out melting: be that raw material advances melting with iron, carbon, manganese, silicon, chromium, aluminium, sulphur, phosphorus, rare earth, smelting temperature is 1580～1620 ℃, and molten steel is cast, 1560～1580 ℃ of casting and pouring temperature; After completing, casting quenches at 900 ℃, temperature retention time 2 hours, and carry out tempering, temperature after quenching is completed: 450 ℃, temperature retention time: 4h obtains bucket lip for drill rod of breaking hammer;
During melting, each material is by percentage to the quality: carbon: 0.27～0.30 ﹪, and manganese: 0.8～1.1 ﹪, silicon: 01.50～1.70 ﹪, chromium: 1.40～1.60 ﹪, aluminium :≤0.08 ﹪, sulphur, phosphorus≤0.03 ﹪, rare earth Re:0.01 ﹪, surplus is iron.
When the present invention uses, machining is made on drill steel 3 tops, be processed into taper shape, insert chamber 2 with the drill steel of bucket tooth body 1 and match, the drill steel that during use, drill steel 3 is sleeved on bucket tooth body 1 inserts in chamber 2, need not weld, vibrations principle according to quartering hammer, drill steel 3 inserts coordinating along with the motion of drill rod is overlapped tighter and tighter between chamber 2 with drill steel, can not come off, and substitutes drill steel 3 by operate portions 4 and carries out crushing operation.Bucket tooth through long-time wearing and tearing after, if need to change, only need the joint portion of suitably beaing bucket tooth body 1 and drill steel 3 with outer, bucket tooth body 1 is namely tear-away, need not dismantle quartering hammer drill steel is carried out integral replacing, the saving of labor, save time, laborsaving.As long as drill steel 3 can use, just only need periodic replacement bucket tooth body, the price of a bucket tooth only accounts for 1/10 of a drill rod cost, and the service life of bucket tooth is almost basic identical with the service life of drill rod, and the bucket tooth inner chamber is little to the drill rod wearing and tearing, drill rod can use for a long time, greatly reduces production cost.
